Description

Wedge type trench cover {WEDGE TYPE TRENCH COVER}

The present invention relates to a trench cover installed in the upper part of the drainage channel and the trench for draining and collecting rainwater or sewage, and more particularly, in an installation site such as the environment, constraints, and conditions of the trench. Regardless of the deformation or design change of the trench support frame caused by the situation, it is possible to install easily, easily and robustly, and to minimize the occurrence of noise and flow and noise caused by friction or impact after installation, as well as to prevent departure and theft. For wedge type trench covers.

In general, trenches for draining and collecting rainwater and sewage are installed at outdoor edges of roadsides and various buildings, including entrances and edges of parking lots, and openings in upper portions of pedestrians' feet or wheels of vehicles or other dirt. A so-called trench cover is provided to prevent the trench from falling out or entering the trench.

1 is an example of a trench cover according to the prior art (Korean Registered Utility Model Publication No. 0342685), and ribs 11 are repeatedly formed on both sides of the body 10, and both ends of the body 10 are formed. Concave portions 12 and convex portions 13 are formed to connect with other trench covers, and concave portions or concave portions of other trench covers are formed by forming connecting holes 16 inside the concave portions 12 and convex portions 13, respectively. It is configured to be connected to each other to correspond to each other with a bolt (15) and a nut.

However, in the conventional trench cover as described above, the recessed portion 12 and the convex portion 13 formed on both sides of the trench cover and the other trench cover adjacent to each other are combined with the bolt 15 and the nut one by one. Since it must be seated and assembled on the supporting frame (not shown) installed on the inner top of the trench, it requires much time and labor for connection and installation work, and it is not applicable to the curved trench because of its structural characteristics that can only be connected in a straight line. There are limitations in use.

In addition, when several trench covers are connected in succession, the recesses 12 on both sides are closely contacted with the convex portions 13 of the other covers adjacent to each other, and thus, the installation width cannot be adjusted. There is no choice but to flexibly cope with the gap caused by the deformation and processing error of the supporting frame caused by the condition.

In addition, the trench cover is designed to have a width slightly smaller than the width of the support frame in the manufacturing process for easy installation in the field.In case of installation in a place where the influence of external force is frequent, such as the entrance of a parking lot where the vehicle passes frequently, Due to the gap with the frame, there is a problem of collision and friction noise while easily flowing and shaking.

Moreover, even though the installation is completed due to the structural nature of the bolt 15 and the nut that connect the trench covers to the outside, it can be easily removed using a tool such as a wrench. There are also problems that are easily deformed or fatigued by frequent bidirectional stresses.

As shown in Figure 2 to 6, the trench cover according to the embodiment of the present invention is largely configured to include a horizontal portion 100, the hook portion 200, the guide portion 300 and the wedge 400. .

The horizontal portion 100 has a predetermined curvature and is formed to cross the support frame F of the trench in a curved shape that is convex upwardly, and both sides smoothly drainage and at the same time as the heel of the high heel. The vertical portion 110 of the shape that can prevent the elongated object is pinched is formed integrally a plurality at a position slightly lower than the radius of curvature at a predetermined interval.

Here, the upper surface of the horizontal portion 100 and the vertical portion 110 may be formed with an uneven portion or a non-slip pad to prevent slipping, the lower surface ribs or stiffeners to enhance the strength and increase the rigidity In one embodiment, the vertical portion 110 may be disposed and formed to form a shape in which the vertical portion and the male and female of the adjacent trench cover correspond to each other.

And the horizontal portion 100 is the same as the function of the speed bumps and safety guides in the entrance and exit of the vehicle or alleys when applying a variety of colors or luminous paint having a meaning of danger or warning on the upper surface due to the morphological characteristics formed upwardly convex The effect can be obtained incidentally.

In addition, the object such as the top surface of the horizontal portion 100 and the wheel of the vehicle is minimized by the radius of curvature of the contact between each other to reduce the friction noise generated during contact, and to distribute the load from the vehicle stably and uniformly It is possible to improve the stress by the load such as to prevent the concentrated or the eccentric load and to improve the durability.

Hanging portion 200 is formed integrally at both ends of the horizontal portion 100 so as to span on the support frame (F) of the trench, the inner side of the support frame (F) when the wedge 300 is not used and applied At least one of the clearance adjusting projections 210 are formed at regular intervals on the side facing the wall so as to be in close contact therewith and to adjust the installation clearance.

That is, when the width between the clearance adjusting projections 210 on both sides is greater than the width of the supporting frame (F), the operator receives a portion of the clearance adjusting projection 210 by using a tool such as a string or grinder and the width of the supporting frame (F). The grinding width can be removed by the corresponding length so that the installation width can be easily changed as required.

In addition, the vertical portion 110 formed on both sides of the horizontal portion 100 between the hook portions 200 has a connection hole 120 and a connection pin 120 having a male and female coupling corresponding to each other in order to connect with another adjacent trench cover. 130 is integrally formed.

That is, as shown in Figure 5, by connecting the connection hole 120 and the connecting pin 130 can be installed in another trench cover continuously as well as being in close contact with each other, the trench cover is respectively flow by the external force Can be minimized.

Here, the connection hole 120 and the connection pins 130 are formed in a pair at regular intervals, and in particular, the connection hole 120 is formed by forming a plurality of continuous holes or penetrating up and down so that one side when installed in a curved section, etc. The coupling position of the connecting hole 120 and the connecting pin 130 and the coupling position of the other connecting hole 120 and the connecting pin 130 may be different from each other, thereby adjusting the installation spacing between each other, thereby providing a more stable installation state. Can be maintained.

In addition, the bottom surface of the hook portion 200, that is, the portion in close contact with the upper surface of the support frame (F) is elastically deformed when receiving an external force while the shock absorber (not shown) to absorb and mitigate shock and noise freely by external force or It can also be combined so that they do not break off easily.

That is, the cushioning material is closely adhered to the support frame (F) and elastically responds to the load or impact force, thereby preventing the lifting phenomenon due to unbalanced contact with the support frame (F), as well as friction due to shake and looseness caused by external force. Noise can be absorbed and mitigated more effectively.

Guide portion 300 is formed in the shape of a groove-like shape in which a portion of the upper surface of the hook portion 200 is opened in at least one or more of the hook portion 200 to guide the vertical sliding movement of the wedge 400 In addition, the guide wall 310 for guiding the wedge 400 to be slidably moved in the vertical direction is formed on the inner wall thereof so as to be inclined so as to be close to the support frame F while the width gradually narrows from the upper side to the lower side. have.

In this case, when the guide parts 300 are formed on each of the hook parts 200, the guide parts 300 are preferably formed to be symmetrically positioned with each other.

In addition, of course, the guide part 300 may be formed in plural pieces at regular intervals along the length direction of the hanging parts 200.

The wedge 400 descends along the guide part 300 while the guide rails on both sides of the guide rails are fixed on both sides so as to couple and fix the gap between the footrest 200 and the support frame F by contact force with the inner wall surface of the support frame F. A rail groove 410 having a shape corresponding to 310 is formed.

That is, the rail groove 410 is inclined so as to gradually space closer to the support frame (F) from the upper side to the lower side is formed narrow in width.

Therefore, the wedge 400 descends naturally along the guide part 300, and the outer surface thereof is in intimate contact with the inner wall surface of the support frame F, and is separated by being moved or lifted up even under external force after installation due to the contact force. And it can prevent the jumping out to improve the safety, and can minimize the generation of noise and vibration due to shaking or friction.

In addition, it is possible to completely prevent the loss and theft by sneak thieves because it is not possible to lift several assembled state in the form of one unit without using a separate mechanical equipment.

In addition, as shown in Figure 6, one side of the wedge 400 facing the inner wall surface of the supporting frame (F) is inclined so that the gap with the inner wall surface of the supporting frame (F) gradually increases from the upper side to the lower side. The inclined surface 430 is formed.

That is, since the inclined surface 430 selectively adjusts the contact distance between the wedge 400 and the support frame (F), it is more easily and effectively applied without assembly defects due to machining and assembly errors without being affected by various installation places. Can be installed.

In addition, an auxiliary rail groove 420 is formed between the inclined surface 430 of the wedge and the rail groove 410 to be slidably moved along the guide rail 310 of the guide part, and the wedge is formed on the upper surface of the wedge 400. The handle 440 is integrally formed to facilitate gripping or the like when inserted into the 300.

On the other hand, the horizontal portion 100, the hook portion 200, the guide portion 300 and the wedge 400 is excellent in tensile strength, elongation, etc. is excellent in vibration and shock absorption, and has a hardness that can withstand the load of the vehicle, etc. It is preferable to form a cast iron metal such as Ferrous Casting Ductile, but the present invention is not limited thereto, and may be formed and processed into a material such as a metal metal or a rolled steel.

In addition, the cushioning material may use a conventional rubber material, but any material may be used as long as it sufficiently exhibits the functions of shock absorption, slippage, and noise prevention required by the present invention, such as materials recycled from waste tires.

Referring to the installation and operation of the trench cover according to an embodiment of the present invention configured as described above are as follows.

As shown in FIG. 5, the trench cover is seated along the longitudinal direction of the support frame F seated on the upper portion of the trench, or adjacent to each connection hole 120 while arranging several trench covers in a row. By inserting and connecting the connecting pin 130 of the other trench cover to be assembled and installed in one unit form.

At this time, when several trench covers should be bent at a certain curvature according to the terrain of the installation place or a design for implementing an optimal design, one connection hole is connected when one cover and another trench cover are adjacent to each other. 120) and the connecting pin 130 by adjusting the rotation angle and the installation interval appropriately to the axis, and then can be easily installed in a variety of patterns, such as curves by adjusting and changing the connection position of the other connecting hole and the connecting pin.

Thereafter, one side of the wedge 400 is inserted into the guide portion 300 and the other side is forced to descend by forcibly pressing or striking an external force while being positioned upward between the hook portion 200 and the support frame F. A strong contact force is generated with the inner wall surface of the support frame (F), and then a portion of the support frame (F) that is in close contact with the wedge 400 is coupled in a slightly deformed state, thereby maintaining a more firm fixing state. .

The wedge 400 may be installed in the same manner as described above in the state in which the wedge 400 is inserted into each of the guide parts 300 on both sides according to the installation interval of the support frame F or the like.

As described above, the trench cover according to the embodiment of the present invention maintains a solid and stable fixed state without easily squeezing in the width and vertical directions even when subjected to impact from the outside after construction and installation, and minimizes the occurrence of noise and vibration as well as rejection. Without using a tool such as can not be removed from the support frame (F) can be prevented in advance to lose and stolen.
